Two North American equity benchmarks ended the week telling different stories. The S&P/TSX Composite closed Friday at 35,789.09, gaining 183.82 points on the day and 0.5% for the week. The Nasdaq Composite lost 3.4% for the week, its fourth consecutive weekly decline. The difference was not an all-clear signal for Canadian equities; it was a vivid demonstration of how sector weights change the transmission of a global selloff.
Mining Provided the Counterweight
Reuters reported that TSX materials shares advanced 11.4% over the week and 2.6% on Friday, supported by a rebound in gold and mining shares. Canadian technology gained 1.8% on Friday as US technology recovered some of Thursday's losses. Financials finished Friday 0.2% lower and industrials fell 0.9%. That breadth is important: the index's positive close did not mean every large domestic sector participated.
In the United States, doubts about AI capital spending, financing costs and possible regulatory scrutiny after the midterms drove the week's technology retreat. Friday's 4.2% rise in the Philadelphia Semiconductor Index could not erase the Nasdaq's weekly loss. Investors comparing the two countries should therefore compare sector and factor exposures rather than conclude that geography alone created the performance gap.
What the Divergence Means for Portfolio Construction
A Canadian-heavy allocation may reduce direct exposure to US megacap technology, but it can introduce greater concentration in financials, energy and materials. Gold miners can offset technology weakness for a time; they also bring commodity, operating and currency risks. The apparent hedge is conditional, not permanent.
For advisors, use this week's contrast to review total portfolio exposure on a look-through basis. Measure US technology weights across funds, Canadian resource exposure, currency hedging and the share of portfolio risk attributable to a few industries. Rebalancing decisions should follow the client's strategic allocation and liquidity needs, not a single week of cross-market leadership.
